The computation of diluted earnings per share (EPS) excludes the effect of the potential exercise of stock awards, including stock appreciation rights and stock options, when the average market price of the common stock is lower than the exercise price of the related stock awards during the period because the effect would be anti-dilutive. In addition, the computation of diluted EPS excludes the effect of the potential release or exercise of stock awards when the awards’ assumed proceeds exceed the average market price of the common shares during the period. For the quarter and nine months ended September 30, 2025, the number of stock awards excluded from the computation was 0.7 million and 1.9 million, respectively. There were no stock awards excluded from the computation for the quarter ended September 30, 2024, and the number of stock awards excluded from the nine months ended September 30, 2024 was 6.4 million.
